DESCRIPTION
The IDT5V5216 is a transceiver which can interchange data across
multipoint data bus structures.
The device has selectable LVTTL/LVPECL/LVDS drivers and
receivers, a selectable Type-1/Type-2 M-LVDS receiver and M-LVDS
driver. It translates between LVTTL/LVPECL/LVDS signals and M-LVDS
signals. The drivers and the receivers can be enabled or disabled by
external pins. The M-LVDS driver is capable of driving bus load from 30
Ω to 55 Ω. The M-LVDS interface allows common-mode voltage range
of -1 V to 3.4 V.
